The electronics market is growing constantly and so is the demand for increasingly compact and efficient power electronic systems. The predominant electronic components based on silicon will in the foreseeable future no longer be able to meet the increasing industrial requirements. This is why scientists from the university of Freiburg, the Sustainability Center Freiburg and the Fraunhofer-Gesellschaft have joined forces in order to explore a new material structure that may be better suited for future power electronics.

Open-cell materials, such as metal and ceramic foams, have been extensively utilized in high-temperature applications due to their light weight, good flow-mixing capability, and ability to cover a large surface area. They are commonly composed of interconnected solid struts and accessible void spaces

The era of electromobility presents new challenges which must be mastered by both man and materials. Today, neodymium-iron-boron-magnets are used in areas in which strong magnetic fields at low volumes and low weights are necessary. These so-called rare earth magnets guarantee the resource conservation of raw materials, weight reduction of the drives and longer service lives required of permanent magnets. However, they are more complicated to manufacture than conventional magnets. A decisive factor for the quality and properties of permanent magnets is a raw material with a narrow particle size distribution with the lowest possible fraction of finest- ( 8 µm).

3D printing and other additive production techniques make it possible to manufacture materials with internal structures of previously unimaginable complexity. This is interesting for lightweight construction, too, as it enables the development of materials that have the highest possible share of interior voids (to make the materials as light as possible) but are simultaneously as robust as possible. Achieving this requires that the internal structures be intelligently organised for maximum efficiency.
